Hi,

yes 2.5 is deprecated. I got it working for PG13 to help people
upgrading. I do not plan to repeat that tour de force again. (There
were lots of minor problems to ignore on the way.)

Debian 11 is new, please use postgis 3 for new setups, or upgrade
postgis first.

Please upgrade to postgis 3 on the old PG version first (or migrate
both PG and postgis at the same time).
